摘要
介绍了铁炭微电解法处理镀锌废水的基本原理及工艺条件,本技术的关键是pH值的控制。铁炭微电解法基建和运行费用低,基本不加或加少量化学药剂(如酸碱),所用填料主要是工业废铁屑,来源广,价格低廉,耗能小,污泥量少,可以实现以废治废,处理后的水中铬(Ⅵ)浓度为0.05mg/L,远低于国家污水综合排放标准(GB8978-1996)第一类污染物最高允许排放浓度。
On the scrap-iron an active carbon-zinc electrolysis treatment of wastewater and the basic principles of process conditions. This technology is the key to the control of pH value. Iron-electrolysis infrastructure and low operating costs, increase the basic or not a small amount of chemicals （such as acidbase）, is mainly used by＇the packing industry scrap debris, the source broad, low-cost, energy-consuming small, less sludge, Waste governance to achieve waste, the water treatment chromium （VI） concentration of 0.05 mg / L, far below the State wastewater discharge standards （GB8978--1996） the first category the maximum allowable emissions of pollutants.
